The Spirit-NOPA® is a family of automated non-collinear optical parametric amplifiers (NOPA) specifically built and optimized for the Spirit® and Spirit® One™ ultrafast lasers. The turn-key, high repetition rate Spirit femtosecond laser combines with the Spirit-NOPA to create a powerful, user-friendly tunable source of ultrashort pulses for high repetition rate ultrafast applications.

Spirit-NOPA is available in four configurations:
The Spirit-NOPA-2H includes a built-in second harmonic generator, to convert the Spirit IR beam to 520 nm. The output of the Spirit-NOPA-2H is tunable from 650 to 900 nm with pulse width as short as sub-25 fs and an output energy up to >3 μJ.

Spirit-NOPA-3H includes a built-in third harmonic generator and its output is tunable from 500 to 800 nm with a pulse width as short as sub-25 fs and an output energy up to >0.5 μJ.

Spirit-NOPA-IR includes a built-in second harmonic generator and its output is tunable from 1200 to 1600 nm with a pulse width as short as sub-50 fs, an output energy up to >0.6 μJ, and peak powers up to >10 MW.

Spirit-NOPA-VISIR provides a broad tuning range of 650 nm to 900 nm (signal) and 1200 nm to 2500 nm (idler). The Spirit-NOPA-VISIR comprises two amplification stages seeded by white-light continuum and pumped by the second harmonic of the Spirit. The first amplification stage is non-collinear, which generates broad bandwidth, and the second amplification stage is collinear, which generates the broad tuning range. The signal output can be compressed to <70 fs using an external prism-based compressor unit, and the idler output to <100 fs, using a bulk compressor integrated into the housing.

Spirit-NOPA is fully computer controlled to allow for easy wavelength tunability. Its built-in bandwidth selector and integrated computer controlled compressor provide a pulse width agility unmatched by other ultrafast laser technologies.

Spirit-NOPA can be factory optimized for a wide range of pump pulse energies to allow for multi-color high repetition rate experiments.
